Be it known that VVliL'r m Brno-K, a citizen of the United States, residing at Eaton, in the county of Delaware and State of Indiana, has invented certain new and useful Improvements in Float Valves, oi

. which the following is a specification.

tering troughs, for the purpeseof maintaiuing'a desired water level in such troughs.

ilxllOlillGl' object of the invention resides in an automatic float wherein the liquid supply passes through the float and is con trolled by a valve located beneath the float and responsive to therise and fall. of the latter. l n inany prior devices, the lioats proper are located beneath the valve struc ture and 'required guides ota relatively lined chz'iracter which are likely to cause irregular operation on the part of the floats. By the present invention, the Heat is guided by an axially extending support through which water or other liquid from a relatively elevatcd source of supply is longitudinally passed.

her a more complete understanding of the invention, reference is to be had to the following description and the accompanying drawing, in which similar characters of reference denote like and corresponding parts throughout the several views thereof.

ln said drawing:

Figure 1 is a. vertical sectional view taken through the improved float valve comprisingthe present invention, and disclosing its adaption to the watering trough.

Figure '2 is a horizontal sectional View taken on the plane indicated by the line 22 or Figure l, and,

Figure 3 is a top plan view of the float.

Referring more particularly to the details of the invention, there is provided a float valve structure designated generally by the numeral In its preferred form, this structure consists of a metallic limit :2, which includesa semi-spherical body 25 havingfa conveved top 4, which is united in a fillltl lilgh ll inanner with the body by the interfittin'g peripheral heads 5. Extending axially and vertically through the float 2 is a tube 6, having its upper endsecured as at? to an upstanding collar 8 integrally fOflQlGCl with atop 5L. The lower portion of the tube 6 is relatively enlarged as at 8 and an annular shoulder 10 is thereby formed at thejuncture between the upper and lower portions or" the tube 6.

The enlarged lower end of the tube projects axially through and is suitably secured to a d nding tubular extension 11 inter, ly formed upon the lower axial part of the body 3, the extreme lower end of said tube being inaterially spaced from the lower end of the float proper. In this depending trei'ne lowere'nd of the tube 6, which l ignated the numeral 12, there is provided a plurality of ports 13, and beneath the ports the end 12 is threaded as atl-t for the reception of a closure cap 15. A rubber or other gasket 16 is confined between the inher part of the cap and the lower ed ge of tl'ietubefo. This gasket may be renewed itronrtirnc "to time by the mere removal oi: the cap 15 which, by being threaded to-tlie end 12, can be readily ellected.

Arranged to extend axially into the tube 6 is a stationary liquid supply pipe 1.? which has its upper end connected or in communication with a suitable source or liquid supply in order that liquid, by the'action of gravity will be permitted to flow through said pipe. The lower end of the pipe 17 is threaded as at 18 for the reception of a relatively enlarged collar 19, which is situated within the enlarged portion 9 or" the tube 6, and by reason of the threaded con nection 18, it will be apparent that collar 19 may be adjusted relatively to the gasket 16. It will be apparent that by this construct-ion the rise and fall of the float 2 will control the relationship between the gasket 16 and the lower end of the collar 19, thereby, in turn, governing the flow of liquid through the ports 13. In the use of the valve shown in the accompanying drawing, there is provided a stock watering trough wherein is included a superposed water receptacle 20 to the lower part of which the upper end of the pipe 17 is connected. The float structure 2 is situated for vertical movement within the float chamber 21 f the Watering trough 22, and is separated from the drinking chamber 23 of said trough bynieans of an apertured partition wall 2 When thus employed, it will be apparent that water from the receptacle J) will be permitted to flow by gravity into the chamber 21, passing through the ports 13,

and from the chamber 21 the water will pass intothe drinking chamber, 23 byway of the apertures in the Wall 2%. hen the water level within the chambers 21 and 23 reaches a predetermined height, the float, by reason of its buoyancy, will rise in the chamber 21 until the gasket 16 abuts upon the lower end of the collar 19, thus shutting off further water flow from the receptacle into the trough 22. As the water in the chamber 23 is consumed, the valve structure will automatically operate, in an apparent manner to maintain a uniform level in the chamber 23 as long as the receptacle 20 is supplied.

with the requisite amount of liquid. It is to be understood, howeventhat while the valve structure maybe admirably utilized in a watering trough of this character, nevertheless, the said valve structure is capable of being employed for numerous other uses. with the same degree. of facility and efliby Water-level, will be precluded.

with peripheral guides, common in many prior structures and that in the present construction Water or liquid will flow centrally through the float-and not around the same. Again, positive action on the part of the valve structure is secured by the absence of undue friction between the float and its guide so that sticking of the float in such manner as to render the same unintluenced The location of the valve beneath the float, instead 01'? over the same is also an added structural advantage.

What is claimed is: r

l. A float valve structure comprising a hollow buoyant float member, a tube. ar ranged to extend axially through-said float member and to project beneath the same, the said lower projecting end of said tube being provided with a port, a closure for the lower end of said tube, a stationary liquid supply pipe extending into said tube, and an adjustable sleeve carried by the lower end of said pipe and movable toward and away from said closure. 7

2.. Afloat valve consisting of a float memher, a tube extending axially throughsaid float member, the lower end of said tube being relatively enlarged and arranged bee neath said float member, the enlarged lower end oi. said tube being provided with ports, acap threaded upon the lower end of said tube, a gaslret between. said cap and the lower end of said. tube, a liquid supplying pipe extending axially of said tube, and a collar adjustably carried by the lower end of said pipe and adapted 'for cooperation with said gasket.

In testimony whereof I .aflix my signature.
